Abstract

The utility model discloses an evaporative cooling type water chilling unit. A return circuit of a refrigerant is formed by sequentially connecting a refrigeration compressor, an evaporative cooling condenser, a throttling valve and an evaporator. The evaporative cooling condenser comprises a fin type precooler, a condensing coil, a condensing fan, a spraying water pump and a water sprayer, the fin type precooler is connected with the condensing coil to form a passage, the condensing fan is arranged near the condensing coil and cools the condensing coil, the spraying water pump is connected with the water sprayer, and the water sprayer is arranged above the condensing coil to spray the condensing coil. The evaporative cooling type water chilling unit integrates two hear exchange forms of air cooling and water cooling, heat exchange efficiency is improved by 25%, cold supplying amount is increased by 15%, and the power consumption of the water chilling unit is reduced by 7-8%.

Description

Evaporation cooling type cold water unit

Technical field

The utility model relates to a kind of handpiece Water Chilling Units, and particularly a kind of evaporation cooling type cold water unit, belongs to field of mechanical technique.

Background technology

Referring to Fig. 1, the refrigerant gas of the HTHP that the compressor 1 of existing handpiece Water Chilling Units is discharged enters condenser 2 by pipeline, by condensation of refrigerant being become to liquid with cooling water heat exchange, flowing to choke valve 3 by pipeline again carries out entering evaporimeter 4 after step-down cooling throttling, in evaporimeter 4, carry out heat exchange with the chilled water that enters evaporimeter, after the cold-producing medium draw heat evaporation of low temperature, get back to compressor by pipeline again, complete a kind of refrigeration cycle, and the water that enters evaporimeter siphons away because of cooled dose of heat, temperature is reduced to user's serviceability temperature, supply with user by delivery port again.The condenser of the handpiece Water Chilling Units of this mode carries out condensation by cooling water by cold-producing medium, the caloric requirement that cooling water is taken away is discharged, so must could normally move by supporting outdoor cooling tower, cooling water leads to outdoor cooling tower, after cooling tower heat radiation, condenser is got back in recirculation, the auxiliary accessories that this way needs is a lot, an if supporting handpiece Water Chilling Units, need to configure a cooling tower, at least 2 high powered water pumps, steel conduit, the parts such as valve, the installing engineering amount of these parts is huge simultaneously, cost cost is very large, and floor space is larger, maintenance cost is high.

Utility model content

Utility model object: the purpose of this utility model is in order to solve above the deficiencies in the prior art, and a kind of evaporation cooling type cold water unit is provided.

Technical scheme: evaporation cooling type cold water unit described in the utility model, its objective is such realization, a kind of evaporation cooling type cold water unit, comprise refrigeration compressor, evaporation refrigeration type condenser, choke valve and evaporimeter, described refrigeration compressor, evaporation refrigeration type condenser, choke valve and evaporimeter connect to form the loop of cold-producing medium successively.

Described evaporation refrigeration type condenser comprises finned forecooler, condenser coil, and condenser fan, feeding spraying pump and water jet, described finned forecooler is connected with condenser coil, composition path, described condenser fan is dispelled the heat to condenser coil near being arranged on condenser coil, described feeding spraying pump is connected with water jet, and water jet is arranged on condenser coil condenser coil is sprayed.

As optimization, the quantity of described finned forecooler is 2, being angle arranges, described condenser fan is arranged between 2 finned forecoolers, condenser coil is arranged on the below of 2 finned forecoolers, make condenser fan produce airflow passes condenser coil and 2 finned preheaters between gap.

Operation principle: first the gas of the HTHP that refrigeration compressor is discharged enter finned forecooler, carry out cooling down in advance by condenser fan, then enter into again condenser coil, water is squeezed into water jet by feeding spraying pump, and water jet is evenly sprayed to condenser coil surface, forms moisture film in condenser coil outside, then carry out cross-ventilation heat exchange by cooling fan again, moisture film evaporates in heat transfer process, siphons away the heat of coil pipe inner refrigerant, thereby reaches the effect of condensation.Condensed cold-producing medium flows to choke valve again, continues kind of refrigeration cycle.

Beneficial effect: evaporation cooling type cold water unit described in the utility model the is integrated parts such as condenser and supporting cooling tower of common unit, reduce engineering construction amount 30%, can reduce the construction area that cooling-water machine occupies simultaneously, economize the land resource.The application of especially distinctive evaporation refrigeration type condenser, integrated air-cooled, two kinds of heat exchange forms of water-cooled, heat exchange efficiency promotes 25%, promotes 15% for cold, and cooling-water machine wasted work reduces 7-8%.
